中文摘要：

以丙烯酸（AA）、丙烯酰胺（AM）为单体，采用水溶液聚合法制备了低黏度聚（丙烯酸-丙烯酰胺）P（AA—Co—AM）树脂。使用旋转黏度计和热重分析仪等测试了树脂的性质，并以该树脂为连接料，制备了新型水性氧化铟锡（ITO）蚀刻油墨。探讨了该油墨的保水性、pH变化和蚀刻图像解析度等。结果表明：通过优化合成工艺可制备分子量适宜的P（AA—CO—AM）树脂，它在150℃以下无分解现象；油墨在使用3h后失水率仅为3．68％-5．34％，存放60d后pH基本无变化，且丝网印刷效果明显好于市售油墨。

英文摘要：

The low viscosity poly （acrylic acid-acrylamide） （P （AA-co-AM）） resin was synthesized by solution polymerization using acrylicacid and acrylamide as the monomers. The properties of the resin were characterized by rotational viscometer and thermogravimetric analyser. A new type of indium tin oxide （ITO） etching ink was prepared using P（AA-co-AM） resin as connection material. The water retention property, pH change and etched image resolution of the ink were evaluated. Results showed that the suit- able resin can be prepared by optimizing the synthesis process. The so prepared resin didn＇t decompose beneath 150 ℃. The water loss rate of the ink was range 3.68% and 5.34%after exposing to air for 3 h. The image resolution used this ink was better than the commercially available ink after storing 60 d. More over, the etching capability did not decline and pH value almost did not change.
